KOI-5, also known as TOI-1241, is a triple-star system about 1,870 light-years away in the constellation Cygnus. A gas giant planet, KOI-5 Ab, was confirmed orbiting the primary star (component A) via the transit method. The planet has a mass of approximately half that of Saturn and an orbital period of about 5 days. Its orbit is significantly misaligned with the orbital plane of the companion star KOI-5 B, suggesting gravitational perturbation during its formation or migration. The system consists of the planet-host star A and its close companion B (orbiting each other every 31 years), plus a third star C orbiting the inner pair every 430 years.
